Reduce crankcase emissions with high-efficiency OCV and CCV systems

MINNEAPOLIS, Minn. (March 12, 2008) — As allowable tailpipe emissions standards are lowered, original equipment manufacturers can look to Donaldson Company, (NYSE:DCI), a leading worldwide manufacturer of filtration systems and parts, for creative solutions for Open Crankcase Ventilation (OCV) and Closed Crankcase Ventilation (CCV) filtration solutions. Donaldson Engine Systems & Parts is introducing two new plastic SpiracleT Crankcase Filtration Systems (CFS) models at the 2008 CONEXPO-CON/AGG Show in Las Vegas in March.

The Spiracle CFS removes crankcase aerosol and particulate using Donaldson's proprietary SynteqT XP, a breakthrough new media that has a lower operating pressure drop, higher overall efficiency (>95%) and longer filter life compared to traditional media. Spiracle CFS systems reduce blow-by emissions generated from an open crankcase vent and prevent fouling turbochargers or intercoolers in CCV systems.

Spiracle CFS also reduces in-cab fumes and draft tube "road drips," keeps the engine enclosures free from oil film and reduces engine oil consumption. Spiracle CFS is a serviceable filtration system that employs a custom-designed pressure regulator in CCV systems to reduce excess vacuum and custom-designed pressure relief value to prevent excessive crankcase pressure build-up.
